Our collaboration with Vortex optics brings you a selection of upgraded scope packages featuring their Crossfire II scope. Crossfire II 3-9x40 Riflescope with Dead-Hold BDC Reticle. With long eye relief, a fast-focus eyepiece, fully multi-coated lenses and resettable MOA turrets, there's no compromising on the Crossfire II. Clear, tough and bright, the hard anodized 1-piece aircraft-grade aluminum tube is nitrogen purged and o-ring sealed for waterproof/fogproof performance. The Dead-Hold BDC Reticle's customized hashmark design helps eliminate guesswork on holdover and windage corrections. Good at varying ranges where estimating hold over is a concern.
